Some comments on India's heat

On May 5, a couple people from BBC World reached out to me, presumably after reading my piece last week on the heatwave in North India and the wet-bulb temperature, for a few comments on a story they were producing on the topic. They had five questions between them; I’m reproducing my answers roughly verbatim (since I spoke to them on phone) below.

Are these high temperatures usual?

A: Yes and no. Yes because while these numbers are high, we’ve been hearing about them for a decade or so now – and reading about them in news reports and hearing anecdotal reports. This isn’t the first such heatwave to hit India. A few years ago, peak summer temperature in Delhi touched 47º C or so and there were photos in the media of the asphalt on the road having melted. That was worse – that hasn’t happened this time, yet. That’s the ‘yes’ part. The ‘no’ part has to do with the fact that India is a large country and some parts of the country that are becoming hotter are probably also reaching these temperatures for the first time. E.g. Bangalore, where I live, is currently daily highs of around 35º C. This is par for the course in Chennai and Delhi but it’s quite hot for Bangalore. This said, the high heat is starting sooner, on this occasion from mid-March or so itself, and lasting for longer. That has changed our experience of the heat and our exposure. Of course, my answers are limited to urban India, especially to major cities. I don’t know off the top of my head what the situation in other parts is like.

The government has said India has a national heat plan and some cities have adopted heat action plans. Are they effective?

Hard to say. Only two score or so cities have adopted functional heat action plans plus they’re cities, which is not where most of India lives. Sure, the heat is probably worse in the urban centres because of the heat island effect, but things are quite poor in rural areas as well, especially in the north. The heat also isn’t just heat – people experience its effects more keenly if they don’t have continuous power supply or access to running water, which is often the case in many parts of rural India. The benefits of these action plans accrue to those who are better off, typically those who are upper class and upper caste, which is hardly the point. When North India’s heatwave was underway last week, NDTV interviewed shopkeepers and small scale traders, vendors, etc. about whether they could take time off. All of them without exception said ‘no’. Come rain or shine, they need to work. I remember there being vicious cyclones in Chennai and waking up in the morning to find the roads flooded, trees fallen down and loose electric wires – and the local mobile vegetable vendor doing his rounds. Also, in urban areas, do the heat action plans account for the plights of homeless people and beggars, and people living in slums, where – even if they’re indoors – they have poor circulation and often erratic water and power supply?

What should the government do?

That’s a very broad question. Simply speaking, the government should give people who can’t afford to shut their businesses or take time off from work the money they’d lose if they did, and rations. This is going to be very difficult but this is what should be done. But this won’t happen. Even during the COVID-19 pandemic, the Indian government didn’t plan for the tens of thousands of migrant labourers and daily-wage earners in cities, who, once the lockdown came into effect, slowly migrated back to their home towns and villagers in search of livelihoods. This sector remains invisible to the government.

[I also wanted to say but didn’t have the time:] the experience of heat is also mediated by gender, geography and caste forces, so state interventions should also be mediated by them. For example, women in particular, in rural India and especially in Central and North India (where literacy is relatively lower) operate in settings where they have few rights and little if any financial and social independence. They can seldom buy or own land and go out to work, and often labour indoors, performing domestic tasks in poorly ventilated residential spaces, venture out to fetch water from often distant sources – a task performed almost exclusively by women and girls –, often have to defecate in the open but do so early in the day or late in the evening to avoid harrassment and shame, which then means they may not drink water to avoid peeing during the day but which would render them vulnerable to heat stress, etc. If state interventions don’t bend around these realities, they will be useless.

[One named government official] said India is tracking heat-related deaths and that these numbers suggest the country is in control of the problem. What’s your sense of this?

The moment you mention data or figures that you say you obtained from this government, the first thought that comes to mind is that it’s probably inaccurate, and likely an underestimate. Even now, the Indian government has an ongoing dispute with the WHO over the number of people who died during the pandemic in India: India is saying half a million but the WHO as well as many independent experts have said it’s probably 3-5 million. For example, if the government is collecting data of heat-related illnesses at the institutional level (from hospitals, clinics, etc.) you immediately have a bias in terms of which people are able to or intend to access healthcare when they develop a heat-related illness. Daily-wagers don’t go to hospitals unless their conditions are acute – because they’d lose a day’s earnings, because their out of pocket expenses have increased or both.

Do you think parts of India will become unliveable in your lifetime?

This is a good question. I’d say that ‘unliveable’ is a subjective thing. I have a friend in Seattle who recently bought a house in what she said was a nice part of the city, with lots of greenery, opportunities to go hiking and trekking on the weekend, with clear skies, clean air and large water bodies nearby. Liveability to her is different from, say, liveability to someone living in New Delhi, where the air is already quite foul, summers are very hot and winters are likely to become colder in future. Liveability means different things to people living in Delhi, London and Seattle. Many parts of India have been unliveable for a long time now, we just put up with it – and many people do because they don’t have any other option – and our bar just keeps slipping lower.
